Aside from short ties to BTs, BOs, BRs, RMs, WCs, etc., they don't see much time out of the truck these days.
You haven't seen much time out of the truck LATELY either. Nor, in the truck for that matter. 😉
Better.

Supposedly, if one double threw the 100' chain, undid the leather wrapping and quickly stuffed it into a glove box, it would spring out in a tangled mess at the unsuspecting target of the prank. Don't ask me how I know this.
Double thrown chains were mostly used for 200' chains using a 10' throw
The pictured 100 ft tape has not jumped back for many years.

This is a single throw (flip)

This is also a single throw even though it was done in 10 ft. loops. Nice chain saw.
yep, had to throw the chain at least once every day during my early career, used a 300 foot chain for right angle topo, 50 foot tape for offsets, had four man crew - one on the instrument - rear chain man - guy on the smart end of the chain with a rod and the crew chief keeping notes.
the 100 foot chain was for measuring between the traverse points prior to doing the right angle offsets.....seems like yesterday

I started out chopping line and using the shovel and pick axe. Then I graduated to the dumb end then the smart end. After I had convinced the PC I had the smart end down I got to look through the transit. After I pestered the I man enough I was taught how to read the vernier. (after work over a few cold ones) I found great pride in closing a section traverse at less than 2 arc minutes after I became I man. Then the first HP distance meter came along. Then the auto read vernier that read out to the arc second. Then the worrisome 0.04' mis-closure. The first crew I was on had two to three rodman, two I man (for double wiggles), an asst PC and a PC. And I double flipped the chain this past weekend.... Like riding a bike.
